Wife falls down when she gets out of bed. She can't remember to pull the cord so someone can come help her. Advice?

If she is using a standard bed there are assit bars available. My mom was having trouble getting in and out of bed. I found a simple L shaped grab bar. Lower part of L slips between box springs and the mattress and other part is vertical and sticks up about 16 inches. It can be placed anywhere along the bed. It has been a great help for my mom. Home medical supply stores usually stock different sizes and styles. Easy to install, no tools needed.

1 WIFE IS IN MEMORY CARE.
2 BED ALARM DOES NOT WORK, IT GOES OFF WHEN SHE GETS OUT OF BED AND FALLS. IT IS ILLEGAL TO RESTRICT PATIENTS.
THANKS FOR YOUR ANSWERS

I believe there is a bed alarm. Also, I know that they no longer raise the sides on the bed, because patients were crawling over them, but it might be worth a try.

Some people have put the mattresses on the floor.

Sounds like she should be in a memory care unit.
